API Design
A New Runtime topic hub collecting signals, patterns, field notes, and public sources about api design.
Retrieval answer
A New Runtime topic hub collecting signals, patterns, field notes, and public sources about api design. API Design is tracked here as an evidence-linked topic, not as a static glossary entry. The page connects raw observations to pattern hypotheses, longer analysis, and public sources. Use it as the canonical landing page before drilling into individual records.

What patterns are emerging?
- high
Agent-ready software exposes capabilities
The agent-ready product boundary is a small set of observable, permissioned capabilities that external agents can compose safely.
Field notes
What should readers understand next?
CopilotKit Brings MCP Tool Calls Into The React Interface
CopilotKit's React integration registers MCP servers with the chat runtime, exposes their tools to the model, and renders tool-call state inside the product interface.
Vercel AI Gateway Adds Runtime Budget Controls
Vercel's July 31 AI Gateway releases combine team and project spend budgets, unified fast mode, Laguna S 2.1 capacity, and updated MCP support into a practical inference control layer.
LangSmith LLM Gateway Puts Runtime Controls Between Agents and Models
LangSmith LLM Gateway turns spend caps, rate limits, fallbacks, redaction, and provider routing into one governed layer for production agents.
Vercel Passport Makes Identity a Deployment Boundary
Vercel Passport is now generally available, adding verified identity tokens, group claims, audit events, and automation bypasses to protected deployments.
LLM Inference Fails Quietly Before It Fails Loudly
Akamai's vLLM load tests show why 200 OK is a weak health signal and why bounded admission, context limits, and an external queue should precede autoscaling.
OpenAI's ARC-AGI-3 Jump Was a Harness Result
OpenAI's ARC-AGI-3 write-up shows why agent benchmarks measure the model plus the runtime harness: retained reasoning and compaction changed both score and token use.
Vercel's mcp-handler 2.0 Makes MCP Servers More Stateless
mcp-handler 2.0 supports the 2026-07-28 MCP spec while keeping older Streamable HTTP clients on the same endpoint and removing Redis or session-storage requirements.
Voicebox Turns Local Speech Into an Agent I/O Layer
Voicebox combines local dictation, transcription, voice cloning, speech generation, profiles, REST, and MCP in one visible bidirectional loop.
OpenAI Splits Transcription Into File and Live Workflows
OpenAI's new transcription guide makes recorded audio and live audio separate product paths, with gpt-transcribe and gpt-live-transcribe as the recommended starting models.
Vercel's Agent Platform Surface Is Becoming a Control Plane
Regional inference, scoped Connect tokens, sandbox forking, and Python WebSockets show Vercel turning agent infrastructure into runtime control surfaces.
Agent APIs Need Fewer Magic Tricks and More Facts
Agent-first APIs should return explicit fields, precise errors, raw facts, and traceable metadata so models can repair tool calls deterministically instead of guessing world state.
